 {\em Notes}: \ssp N = 50. Results obtained from Hamiltonian MCMC implemented in Stan, run with four chains, 2,000 samples per chain, discarding the first 2,000. The coeffcient estimates are the mean of the draws from the posterior distribution and the bounds on the credible intervals are the 5th and 95th percentiles of the posterior distribution. Diagnostics (available on request) indicate convergence.
